← ScienceWhich outcome occurs when airflow around an airfoil reaches critical Reynolds number?
A)Boundary layer transition to turbulence✓
B)Increased laminar flow stability
C)Reduced pressure drag coefficient
D)Enhanced lift force generation
💡 Explanation
Airflow destabilization appears because increases in Reynolds number trigger boundary layer transition. This increased chaotic mixing enhances momentum transfer, therefore, turbulence arises, rather than stable laminar flow, different aerodynamic properties.
